Not sure how old of anything about it.

Found it in some stuff and not sure where else to look. I have a lot of vintage stuff, please! help?? I will put up mors pics later. I did find out that on the inside back piece it says Webster Watch CO. INC
Swiss, on the movement side it has D320 on the left side, on bottom towards the right side it has Webster Watch CO. INC. One 1 Jewel Swiss unadjusted UG. Any information would be great

Thank You, Have a good night
